this is core driver for handling fpga program operation from flash to
fpga manager. I can improve the message. Let me know if you have other
comment need to add.

Okay, i will run checkpatch.

Sorry, i'm not getting you. How functionality be scripted? Could you
provide some example or details explanation?
